11) SMBus Connector (5-1 pin SMB)
This connector allows you to connect SMBus (System Management Bus) de-
vices. SMBus devices communicate by means of the SMBus with an SMBus
host and/or other SMBus devices. SMBus is a specific implementation of an I
2 C
bus, which is a multi-device bus; that is, multiple chips can be connected to the
same bus and each one can act as a master by initiating data transfer.

12) Internal Microphone Connector (3-pin MIC2) (optional)
This connector supports the chassis-mounted microphone to the motherboard
instead of connecting an external microphone to the ATX connector.
NOTE: The internal microphone does not work if there is an external mi-
crophone connected to the external Mic (pink) jack. You may only use one
microphone at a time.
